Myinvention relatesr to separators and has to do particularly with improvements in the type of separator described in my co-pend ing application, Serial No. 72,993, iled December 3, 1925. 1

This 'separator comprises aV stationary screen of substantially cylindrical form within which aresupported a plurality of bowl shaped discs adapted to be revolvel on l0 a vertical axis at a comparatively highrate of speed. ylvlaterial applied to the discs, is

' -thrown or sprayed ofi' theperipheries thereof with such force as to separate the solids "from the liquid as the material strikes the 5 screen. Y

`The principal object of my present invention isv to provide an improved'uid and solids separator.

rAnother object is to causel the material f2() sprayed by the discs to be distributed evenly against thescreen.

Anotherobjectois lto provide improved means for rotatably driving the discs.

YAnother object is to provide an improved 2.5 motor mounting and disc support for such Y separators.

Other objects andfadvantages will appear from a consideration of the following de,- tailed description taken with the accompanying Adrawings wherein-' Fig. 1 is a front elevationalv view', partially in section, vshowing "one embodiment of my invention;

Fig. 2 is a fragmentary reduced size taken on ythe l l, and,

sectional view of line 2 2 of Fig.

Fig. .3 is a fragmentary section onv the lineY -3 of Fig. 1. p y p The separator, comprises a framework formed of upper 4and lower casingslO and 11 respectively,` secured together by bolts 12-12` and a plurality of uprights 13e-1.3 which' are here shown as channel irons secured to the casing 10 by screws A14s-#14.l The uprights are brought together at'their upper extremities to form an arbor support 111, the uprights being secured together at this point in any suitable manner.

through an' aperture "of the arbor support' and is loosely held in place by means of a nut 17. 'An electrical motor 18 carries .at its upper end,-la yoke 19 through which the bolt 15j` is adaptedto'ex'tend and be held in cated cone 27 at the lower extremity thereof,

secured thereto by supports27. These supports are in, the form of blades which are set at an angle as shown in Fig. 3, and thereby serve to elevate material with which they A screen l28', issecured within the casing portion of the frameworky by means of rings 31 and 32 and a pan 33 adapted to be secured `to the lower portion of casing 11, closes the ing a central aperture 35 for the passage of the motor shaft extension, is provided on the upper part ofV the VYcasing 10.

Most of the details `of my improved sepa rator heretofore described, are shown in my co-pending application; but the manner in which a 'separator of .this type functions,

should* possiblyr be made clear before de` scribing the improvementsV which are the subject matter of thepresent case..

The material to' be separated is introduced continuouslyand in'any suitable manner to the disc or discs) 26'. The discs,rev0lving n at a hi'ghrate of speed with the motor, causes the material to fly olf at,y altangent to the periphery thereofl and strike againstV the screen. -A portion of `*the liquid'in'the ma terial, Willpass through the screen by the force of the'impact, and fiow' to the' bottoni ofthe annular trough formed by the lower casingv 11 whence it flowsthrough a properly provided spout. The balance of themaf terial v iiowsl downfthe. inside of,l the screen into the pan 33. `the pan is lled suf! cientlyito lcause ,theV material therein Vto e11-V gagethe bottom edge of the truncated cone 27, such material will be drawn up the inside of the cone-by the kblade supports 27 andinallythrown oifthe upper edge there- Y .of to` strikeV against the screen and thus result in a urther'separating action. It isob'vious .that the discs must be drivenV ata high rate `of speed and accordingly an exact balance-ofjrotatingpartsinust be ob.

tained. vBy suspending theL motor with its shaft bearing the discs, extending vertically downward the'motor may berun Vat avery it centers itselhand finds its own axis of -roatation. umOtlierwise with the motor liXed, if` ythei'shait is 'slightlyroutfof-tbalance it will high rate of 'speed without danger, b ecause whenit is freely suspended'in this` manner vibrate badly, ,and even fly "off-the `center by bending when the condition''beeomes aggra- 4 y Evated.

thereto, but what I claiinpas new and desire to secure by United States Letters Patent is as follows:

1. In a fluid and solids separator a station ary screen, arotatable disc adapted to spray inateri al against the screen, means for receiv-` ing: the material passing through the screen, a pan below the screen for receiving the material not passing through the screen, an inverted rotatablecone extending into the pan having angular blades for withdrawing material from the pan to be sprayed against the screen bythe outer periphery of said cone. v 2. The separator, defined in 'claim l, Wherein saidblades serveas supports to secure said .tone to itsk shaft 3. f The separator defined in claim l,`wheremation wherebythe vmaterial sprayed thereby is distributed evenly on the screen over a comre-sprayit against'the screen, said conehav# ing its top outer edge of uneven conformation wherebythe material sprayed thereby is distributed evenly on Ythe screen over a comparatively large area. i y f 1 l Y In witness whereofl hereunto subscribe my name this 9th, day of April, 1927.v e
